Nerf diamond spawn rate please

In snapshot 21w06a, the new cave generation was added. One problem I had with it was the spawn rate for diamonds. Diamonds are way more common now than they once were and it isn't good for Minecraft's future. Please make diamonds a little rarer so that it will balance the game with the new caves and cliffs update's generation.  Please change diamond's y level for spawning so that they won't be as exposed, why not make them spawn at y-level -52 and below. I just don't see the point why not change the way diamonds spawn in Minecraft.
